Patent DE-3821571-A1 (DE)
Inventor: SETZER HELMUT
IPC: B21B31/18
Filed: 1988-06-25
Abstract: In the hitherto known devices, the axial shifting of rolls in the stand of a rolling mill is carried out on slideways, the sliding friction resistances of the hydraulic shifting machinery arranged externally on the roll stand which occur in the slideways having to be overcome by increased energy consumption. In addition, these roll-shifting devices are of complicated structure and are hard to get at and difficult to maintain owing to the pressure and lever elements which are arranged externally on the roll stand and project a long way outwards. According to the invention, these disadvantages are eliminated in a simple way by the fact that the inner bearing ring (5), fastened to the bearing journal (2) of the roll (1), of the radial bearing (3) in the form of a roller bearing is arranged so as to be axially moveable with respect to the outer bearing ring (7, 8) of the radial bearing (3), and that the shifting system is integrated in the axial bearing (4) as a hydraulic pressure system (16, 20, 22, 23).

Title: Process and device for combined afterburning, denitrification and absorption of exhaust gases from diesel engines and purification of the fresh air supplied to the driver's cab
Inventor: KOCH CHRISTIAN DR ING
IPC: F01N3/04
Filed: 1988-11-10
Abstract: The invention relates to the process and to the device for combined afterburning and denitrification of diesel exhaust gases in a catalyst, the absorption of soot and of the condensable substances, contained in the exhaust gas, in a special absorber by a scrubbing fluid and, in a separate circulation, the purification of the external air by removal of odorous and harmful substances in an impregnated honeycomb body for the driver's cabin.

In a separate circulation, the substances dissolved in the glycerol-like fluid are stripped out with air which is then fed as combustion air to the engine.
Patent DE-3842575-A1 (DE)
Title: Process for preparing chromium carbide powder
Inventor: FINDEISEN EBERHARD G
IPC: C01B31/30
Filed: 1988-12-17
Abstract: The invention relates to a process for preparing chromium carbide powder. JP 61209907 discloses a process for preparing chromium carbide powder, in which calcined chromium oxide is mixed with graphite and water and is then reacted in a container, made of refractory alumina, at temperatures of above 1250@C. This gives a product which contains 97% of chromium carbide and whose particle size is from 5 to 50  mu m. The chromium carbide prepared by this process always still contains chromium oxide as impurity. It is accordingly an object of the invention to prepare a chromium carbide powder containing less than 0.1 % by weight of Cr<2>O<3>. This object could surprisingly be achieved by mixing pure chromium metal powder having a particle size < 63  mu m and carbon in the amounts calculated for Cr<3>C<2>. This mixture was then heated in graphite dishes under a protective gas atmosphere at a temperature of 1200-1600@C for between 1 and 12 hours. The chromium carbide powder formed is freed of free carbon.

Patent DE-3903332-A1 (DE)
Title: Jet (reaction, jet-propulsion) engine combination
Inventor: WEBER FRANZ-JOSEF
IPC: F02K7/16
Filed: 1989-02-04
Abstract: The concentric combination, consisting of a by-pass gas turbine, a number of high-temperature combustion chambers, which have a Laval (convergent-divergent, supersonic) nozzle outlet and are arranged in the form of a rim in the inlet nozzle of a ram-jet engine, of the previously mentioned individual engines and a liquid-propellant rocket is the subject-matter of the main application P 3803876.5. It has the further following imperfections: During operation of only individual high-temperature combustion chambers, the jet pump effect of the combustion gas flows in the annular inlet nozzle of the ram-jet engine is small. Furthermore, the compressor capacity of the gas-turbine compressor for the air supply of the two combustion chamber systems is too low. In addition, the turbine exhaust gas contains a large quantity of pollutants which flow out without hindrance into the environment. A comprehensive jet pump effect is rendered possible in the inlet nozzle of the ram-jet engine by means of only one large-volume high-temperature combustion chamber situated at the middle of the engine. An additional compressor driven by a shaft power turbine supplies air adequately only to the high-temperature combustion chamber. The exhaust gas pipe orifices of the gas turbine are situated in front of the inlet nozzle of the ram-jet engine. The turbine exhaust gas can flow in with the free (outside) air into the ram-jet engine, where it can be subjected to afterburning in a pollution-reducing fashion. The engine is suitable as a motor for supersonic aeroplanes.

Filed: 1989-08-17
Abstract: An acousto-optic later 30 for shifting the frequency of an optical signal comprises a block 32 formed of a dielectric material having an acoustic transducer 34 mounted to a first surface 35 for launching acoustic waves in the block. End face 36, 38 of the block are oriented relative to the first surface such that an optical beam of a selected frequency incident upon one of the end face at a selected angle refracts into the block and is diffracted by the acoustic waves to form an output beam from the block that is collinear with the incident beam and shifted in frequency therefrom. The dielectric block preferably is formed of arsenic trisulphide. The end faces are preferably angled relative to the transducer so that the optical beam incident upon the acousto-optic modulator preferably is parallel to the transducer. The modulator is used in fibre optic ring interferometers which relay on the sagnac effect and are employed as rotation sensors. <IMAGE>

Abstract: Formwork and moulds are described for side supports (11-13, 15-17) to wet concrete in a precast concrete manufacturing process. The precast concrete unit (14) is cast on the steel former table the first procedure is to homogenise and plasticise the clay by adding water, the clay may be either fresh supply or reclaimed from previous castings. The compounded clay is formed into the required cylindrical and edge shapes by use of a extrusion machine or a specific steel or timber former. The clay mould rests on the steel table. Concrete is poured into the mould and excess removed and then trowelled with a steel float. The precast concrete unit is now allowed to harden for between 6 to 24 hours with the use of a drying chamber. The clay mould will have become brittle so that it may be separated from the concrete unit by a gentle knock. This clay residue will now be available for use again in the first step in the production cycle. Plasticine or loamy type of material may be used as a satisfactory substitute for clay dependant on availability. USE/ADVANTAGE - Precast concrete manufacture. Ornate shapes can be formed with the use of only one master template and mould materials recycled. Cost effective and adaptable.
